not very good
Didn't like it. The style was not to my liking, the movement was slow and stiff, and the music was too upbeat. It sounded far too happy for a ninja fight, and reminded me of an 80's cartoon end theme song, you know like some show about magic lemurs who use smiles to brighten the world lol or whatever.
Anyway, I liked the idea, but I think it coulda been executed better.
